Filed: 1932-11-01
Abstract: 407,134. Filing papers. STONE, H. B., 17, Craven Road, Addiscombe, Croydon, and JONES, P. H., Twinlock Works, Beckenham, Kent. Nov. 1, 1932, No. 30768. [Class 146 (i).] In a fastening device for attaching together a sheet retaining plate and a sheet receiving post in a loose-leaf binder, a locking-plate is provided which is rotatable on the retaining plate eccentrically to a hole therein, the locking-plate also having an eccentric hole, which by rotation of the locking-plate can be moved to a position in which it is concentric with the hole in the retaining plate, or to a position in which a part of the edge of the hole in the locking-plate will extend into a groove in the post inserted through the holes. The sheetretaining plate a has a hole b through which the end of the post c can be passed into a cap d permanently or detachably secured, by bending over the lugs h, to the plate a. The locking- plate e is rotatably held within the cap and is formed with an eccentric hole which, when the plate e is rotated in one direction by a lug g projecting through a slot in the cap d, may be brought into register with the hole b, and when rotated in the opposite direction, is brought out of register therewith so that the edge of the hole enters a groove in the post, thereby locking together the post and the sheet-retaining plate a. The locking-plate e and cap d may be mounted on one side of the binder strip j and the plate a on the other side, when the plate e is retained in its adjusted position by friction. Alternatively, the plate a and cap d may be arranged on one side of the strip j and the lug g can be bulged to engage depressions in the plate a to hold the plate e in adjusted position, or the lug may act as a spring tongue to engage notches in the sides of the slot in the cap.

Title: Porous bonded fabrics and processes therefor
IPC: D06N3/00
Filed: 1970-06-25
Abstract: 1323141 Non-woven fabrics UNION CARBIDE CORP 25 June 1970 [27 June 1969] 30995/70 Headings D1R and D2B A porous artificial leather or other non- woven fabric is produced by extruding a blend of immiscible polymers as a rod, tape, filament or other shaped article, formed of a plurality of ultra-fine fibres (i.e. having a denier of less than 0.5 and a diameter of less than 5Á) converting the shaped article into a sheet, heating the sheet to fuse at least some of the fibres, then extracting some of the fibres. The polymers are drawn from 2 or all 3 of the following classes; soft elastomers (e.g., a block polyurethane of polyether segments joined to polyester, polyamide and/or polyurea segments by urethanyl linkages); soft non-elastomers e.g., polypropylene, and hard polymers e.g., polystyrene, nylon 6 or polyvinyl acetate. Further examples of each class are specified. Preferably the hard fibres are extracted, and the elastomeric fibres predominate where artificial leather is required. Rigid boards are produced from hard non-extractable fibres. In example 2, cubes of polyurethane, polypropylene and atactic polystyrene are mixed and melt-spun through a 1" single screw extruder at 180C, the extrudate being chopped and melt-spun through the same extruder into a 1/16" strand which is drawn by a Godet roller, immersed in a 125C glycerine bath and stretched to cause molecular orientation. The strand is cut into staple lengths, dispersed in water, optionally mixed with cotton, nylon, polyester, acrylic or modacrylic staple fibres, beaten to a pulp and wet laid into a sheet. The sheet is air dried, pressed in a heated platen press or by hot calendering, then immersed in one or more baths of toluene to wholly or partially extract the polystyrene. Dielectric heating may, be used. The shaped article may alternatively be formed into a sheet by air laying staple length portions, or by cross-lapping continuous tapes, films or filaments to form a web. The cross laid, preferably orientated, films may be fibrillated by needling. In example 11, a 20 filament continuous filament yarn of polyurethane islands in a polystyrene matrix is stretch orientated and woven. The fabric is pressed at 190C in a platen press at 50 p.s.i. to produce a 2 ml thick melt-bonded sheet, which is then extracted with toluene to remove the polystyrene to produce a soft porous sheet.

Title: Improvements in and relating to amplifier circuit arrangements
IPC: H03G3/22
Filed: 1935-11-13
Abstract: 465,742. Valve amplifying circuits. SIEMENS & HALSKE AKT.-GES. Nov. 13, 1935, No. 31424. Convention date, Nov. 15, 1934. [Class 40 (v)] For automatic volume control the grid bias of an amplifier is controlled so that it is approximately the same for zero and normal signal amplitude and is a monotonic function of said amplitude over a substantial range including the normal amplitude. Such a variation is shown in the curve SVr, Fig. 2, which shows the relationship between signal amplitude Ea and grid bias SV, the grid bias being the same for zero signal amplitude and normal amplitude Ean. The curve SVr is the sum of two potential variations Gl1 and GL2 produced by the rectifiers GL1, Gl2 respectively Fig. 3, which are fed with signals from the output T3 of the amplifier RV and produce opposing voltages in their series-connected load resistances W1, W2 respectively. The signals applied to the rectifier Gl2 are of greater amplitude than those applied to Gl1 and produce an output voltage only when they exceed the voltage Ea1, Fig. 2, of a source GV2 in the rectifier circuit. Other methods of producing the desired grid bias may be used alone or in combination with that described above. They include the use of rectifiers fed through differently biased amplifiers or through glow discharge devices with different starting potentials. Specification 417,608 is referred to.
